Out-of-equilibrium dynamics in AMO quantum simulators

Andrew Daley, University of Strathclyde

Over the past few years, the possibility to control and measure atomic and molecular systems time-dependently has generated a lot of progress in exploring out-of-equilibrium dynamics for strongly interacting many-particle systems. This connects directly to fundamental questions relating to the relaxation of such systems to equilibrium, as well as the spreading of correlations and build-up of entanglement.

Quantum Information Enabled Neutron Interferometry

Joachim Nsofini, IQC

In the quest to explore big quantum systems, there have been opportunities to explore smaller quantum system like the neutron interferometer. A neutron interferometer (NI) has proven to be a useful tool in the study of quantum effects ranging from  experiments with single particle interference to measuring quantities of significant importance in condensed-matter and Standard Model physics.

Dephasing with strings attached

Leonid Pryadko, University of California, Riverside

Is there a difference between the quantum dynamics of a "real" particle and a collective excitation, like that in a spin ice, which creates a measurable gauge field? I will argue that in the presence of weak dephasing, the answer depends on the quantity measured.

This is the sixth of the Intellectual Property (IP) Management Lunch and Learn Lecture Series. We are bringing in thought leaders in the protection and management of intellectual property, including many years of experience in relevant areas of information technology.

This session will be led by Viona Duncan.

The optimality of projections for quantum state exclusion

Abel Molina, IQC

We will first motivate the problem of quantum state exclusion of pure states, through its connections with the PBR game and with compatibility conditions for quantum state assignments. Then, we will discuss our recent result regarding the optimality of projections for perfect state exclusion of 3 pure states in 3 dimensions (arXiv:1702.06449).

A platform to study many-body physics with photons

Hakan Tureci, Princeton University

The past decade has seen enormous experimental progress in building superconducting electrical circuits featuring artificial atoms subject to the quantized electromagnetic field of microwave photons. The fabrication and control of superconducting circuits has reached a stage where many such elements can be wired up into intricate networks, allowing the preparation and readout of complex quantum states of photons and atoms.

This is the seventh of the Intellectual Property (IP) Management Lunch and Learn Lecture Series. We are bringing in thought leaders in the protection and management of intellectual property, including many years of experience in relevant areas of information technology.

This session will be led by Tom Hunter.

Joachim Nsofini of the Department of Physics and Astronomy is defending his thesis:

Quantum science and technology at QuTech (Delft, NL)

Julia Cramer, QuTech Delft

QuTech is an advanced research center for quantum computing and the quantum internet, addressing scientific and engineering challenges in collaboration with industrial partners. QuTech is striving to remain at the forefront in quantum information science and technology. I’ll give some info on the development of QuTech over the years. Furthermore, I will present what the goals and focusses are of our research teams, current work and latest milestones.

On-demand entangled photon sources

Arash Ahmadi

In this presentation I will be talking about the project we have done in our group since last October on the emission of a QD embedded in a nano-wire.
